Tight-rope

Both of them have comdey and yaoi in it. So if you like Sekaiichi Hatsukoi you'll probably like Tight-rope and vise-versa.  

Both have similar relationship where one is the hot headed type, and the other the calm kind one. both funny, and highly enjoyable. You'll love 'Koisuru Boukun' if you liked 'Tight-rope'. ENJOY :D 

Both Shounen Ai (plus a bit yaoi - though it's just "knowing what'll happen or what's happening, than actually seeing it). Both amazing cute couples. Tight Rope "only" has one couple, since it is just a 2ep. OVA, and it is more about protecting each other, than the "daily life" problems in Junjou Romantica. Both are amazing! 

Both are about the friendship between a gang leader and a more ordinary person and involve the gangster protecting his friend who gets dragged into the trouble of a more violent world. The "ordinary" person in both are actually formidable and manly (no wimpy ukes here). The relationships are cute and feel good with some good fights thrown in. 

Similar animation Drama, comedy, yaoi/BL Similar character personalities One is dominant and innocent acting, the other is more silent and shy but often expressionless  

Both of them have to deal with gang and violence, also they are both yaoi but I think Tight rope is much less intense than Okane ga Nai. Also in my opinion Tight-Rope has much better Art.  

If you like one you should like the other ! Both have : - Boys love relations betweens 2 protagonist. - Yakuzas - Fight / injuries - the yakuza guy (seme) try to make some bad jokes - the yakuza's boyfriend (uke) is involved with yakuza problems. 

In both these animes Ukes are strong individuals with strong characters that support their Seme emotionally trough out the relationship... which differs from a typical Uke characteristic to be feminine and frail  

Basically they both come from a family of yakuza and have a certain position to uphold.  

2 guys having a bromance though sakamichi no apollon is just hinted... theyre very similar though .3.
